DESCRIPTION

The TSM112 integrated circuit incorporates all

sensing circuitry to regulate and protect from over

voltage and under voltage a multiple output power

supply (3.3V, 5V and 12V).

TSM112 incorporates all the necessary functions

for Housekeeping features which allow safe oper-

ation in all conditions, and very high system inte-

gration.

TSM112 integrates a precise voltage reference.
